I can say that those mechanism implemented into bitcoin will help itself from collapsing. The difficulty will prevent the miners from mining but it may make bitcoin rarer a bit due to its difficulty (full speculation). However it can sure that halving will decrease the quantity of bitcoin but increase the value which will keep mining profitable and still attract many miners. All those three have some relations and it will help bitcoin survive

The difficulty has no effect on the rarity of bitcoins. The money supply is predetermined.

The halving does not decrease the quantity of bitcoins. The quantity of bitcoins is always increasing as long as the subsidy is more than 0.

well sorry for my opinion about difficulty, like I have said "full speculation" . About the halving part, I mean "quantity" is the supply per block which makes people feel there will be less bitcoin or rarer. It's about feeling which makes the price higher because the amount of bitcoin is predetermined like you have said

More difficulty comes and more halving comes the price will increase if it will happen year by year.. because of the miners are increasing more population the difficulty will increase so it will turn in to not profitable because they are many.. so the solution for this is waiting for the halving so that your bitcoin you earn before are profitable after halving..

1) If the difficulty increases exponentially.2) If in the coming months "halving" will reduce to half the miner's reward.3) If the projections of various spreadsheets indicate that it is not currently profitable mining.

How will continue to operate the system?

Many of the current hardware will no longer be profitable after the halving. So, many hardware will stop mining and the difficulty will probably decrease. Miners like the Avalon and the S7 will still be profitable and new hardware will come in. So miners will still be around for a long time
